我国水资源存在的问题及其防治措施

鉴于水资源服务于人类的各行各业,是人类不可或缺的自然资源,由此研究了我国水资源存在的水多,水少,水脏,水浑四大问题,并根据我国水资源的现状提出了改善四大水问题的措施。     

基于灰色关联分析的达州历年洪灾等级评价研究

针对达州地区洪水灾害,从经济损失、农作物受灾情况、受灾人口、死亡人口、失踪人口和房屋倒塌情况六个方面构建评价指标,应用灰色关联模型计算达州地区近7年的洪灾灾情的关联度,确定每年的洪灾灾情等级。评价结果显示与达州的实际灾情比较相符,从而为当地洪灾灾情等级的综合评价提供依据。     

试论明清江淮地区的水旱灾害与农业耕作的变迁

本文以灾害社会经济史的视角，对明清时期江淮地区的水旱灾害与农业耕作关系作了深入地探讨。笔者以为，频发的水旱灾害不仅造成了江淮大量耕地的丧失和可耕地地力的下降，从而严重阻碍了当地社会经济的发展，还造成了江淮一些地区传统优势种植农业的衰退以及一些地区耕作制度的逆转。     

国外水库设计洪水标准研究

通常根据工程规模、溃坝后对下游潜在危害性及大坝类型等要素来确定设计洪水的标准。PMF作为国外很多国家的设计洪水标准,对于土石坝设计洪水标准的确定可能是适用的,但是对于重力坝则偏于保守。对水利工程而言。在确定设计洪水标准时也应该考虑工程的经济性。     

农事的破坏与补救--近代江南地区的水旱灾害与农民群众的技术应对

近代时期，针对江南地区水旱灾害的威胁，为补救因正常农事活动遭到破坏而遭受的损失，人们采取了一系列的技术措施，如补种、改种相关作物，这在一定程度上反映出人们农业生产活动过程中的生态适应性。     

Floods,food security,and coping strategies: Evidence from Afghanistan

In this paper, we assess the long‐term effect of floods on food security (as measured by calorie and micronutrient consumption) by applying an instrumental variable approach to data from the Afghanistan National Risk and Vulnerability Assessment survey. To identify the determinants of this effect, we also estimate how floods affect per capita yearly household income and poverty status. We find that exposure to flooding during a 12‐month period decreased daily calorie consumption by approximately 60 kcal while increasing the probability of iron, vitamin A, and vitamin C deficiency by 11, 12, and 27 percentage points, respectively. Controlling for price shocks and income only marginally reduces this flood effect on food security, suggesting that impaired livelihoods (rather than price hikes) are its primary driver. We further determine that exposure to this natural disaster decreases income by about 3% and makes flood‐affected households about 3 percentage points more likely to be poor. Lastly, we show that experience of floods is strongly and significantly associated with lower diet quality and quantity, and with engaging in consumption smoothing coping strategies, such as buying food on credit and taking loans. These findings underscore the serious direct impact of floods on both diet and effective behavioral responses to such shocks while emphasizing the need for targeted micronutrient supplementation in disaster relief and food aid measures even after the period of natural disaster emergency.     

城市洪水资源化研究

综合分析城市缺水、城市灾害和洪水资源化,提出城市洪水资源化的概念,并以华南师范大学社区为例,分析洪水资源化的经济效益,建议城市在遵循生态效益最大化的原则下,化害为利,通过城市雨洪收集利用,利用水库、湖泊蓄水,引水输沙,引水冲污等措施实现城市洪水资源化。     

农业巨灾经济影响分析——以我国洪灾为例

洪灾是我国的主要巨灾之一,每年造成了非常巨大的直接经济损失,严重影响到农民的生产、生活和农民增收,也影响到我国的粮食安全,还对我国的农业财政产生了一定的影响。因此,应该加强农业巨灾的风险管理,采用多种"四位一体"的管理体系来分散农业巨灾风险。     

论明清时期苏北里下河自然环境的变迁

明清时期，黄、淮洪水屡屡倾泻苏北里下河。水走沙停，里下河地区的河湖港汉日趋淤塞，并最终导致射阳湖的消失。里下河自然环境亦因此而完成了从泻湖到平畴的巨大变迁，而自然环境的变迁又进一步加剧了水灾的肆虐性。水灾与自然环境变迁交相作用，将里下河引入赤贫的深渊。
